3 Description
The ISO772x-Q1 devices are high-performance, dualchannel
digital isolators with 5000 VRMS (DW and
DWV packages) and 3000 VRMS (D package) isolation
ratings per UL 1577. This family includes devices with
reinforced insulation ratings according to VDE, CSA,
TUV and CQC.
The ISO772x-Q1 devices provide high
electromagnetic immunity and low emissions at
low power consumption, while isolating CMOS or
LVCMOS digital I/Os. Each isolation channel has a
logic input and output buffer separated by a double
capacitive silicon dioxide (SiO2) insulation barrier.
The ISO7720-Q1 device has both channels in the
same direction while the ISO7721-Q1 device has both
channels in the opposite direction. In the event of
input power or signal loss, the default output is high
for devices without suffix F and low for devices with
suffix F. See the Device Functional Modes section for
further details.
Used in conjunction with isolated power supplies,
these devices help prevent noise currents on data
buses, such as CAN and LIN, from damaging
sensitive circuitry. Through innovative chip design and
layout techniques, the electromagnetic compatibility
of the ISO772x-Q1 devices has been significantly
enhanced to ease system-level ESD, EFT, surge,
and emissions compliance. The ISO772x-Q1 family
of devices is available in 16-pin SOIC wide-body
(DW), 8-pin SOIC wide-body (DWV), and 8-pin SOIC
narrow-body (D) packages.
